New Patches Allow More Easily Managing The AMD P-State Linux Driver

This is prime Phoronix for me. Super educational and enlightening. Is it your impression that EPP will one day be the default or recommended-default for Linux with AMD?

I think this is the way most x86 platforms are going. Intel is doing something similar with their pstate driver IIRC.

it's going to be all of them, any of them that have the resources/desire to solve efficiency issues.

ACPI only supports 3 C-states, so, unless that's extended in a vendor-neutral manner, vendor-specific pstate drivers are all that we can hope for

Well one way be if ACPI had some default states in its spec and allowed vendors to expand on it instead of this messs we are in now.
